They probably wouldn't. Didn't the woman in the first one break the rules for a bit over 1 million?
In general the actual dollar amounts in the John wick universe always seemed low to me. I always thought they should have used the gold coins more, since their value was more ambiguous
Alter my appearance as much as possible, as many times as possible. Live on cash. Move location as much as possible, I'll aim to live in my car if I can. Alter my number plate regularly. Get rid of my phone. Live phoneless.

But eventually money will run out. I don't think I would last longer than my savings though. I'd be lucky to live a month.
I was going more in the direction that they are psychos that use you as bait so they can kill whoever dares step on their property 😂
It would probably be illegal to say "i have a billion dollars just lying around here, come and take it" and then shoot people, not so much if you coincidentally let slip that you house the billion dollar guy.
